In a multiple draw plate available to the manufacture of artificial 'silk, 'a'wall plate hayinga threaded hole, an. elastic hollow screw plug fitted into this hole and having-a polygonal head, for]. a wrench, a, conical part in the hollow of the-plug and a cylindrical part adjoining it and intended as a lodging for a draw plate, a draw plate comprising a this stone having acentral aperture for the jet of Viscose and enchas- 6 ing means adapted to secure the working position of the stone. o

2. In a multiple draw. plate availab'l'eto the manufacture of artificial silk, a wall plate havin-ga threaded hole, an elastic 1101- low screw plug fitted into this hole and havinga polygonal head for a wrench, conical part in the hollow of the plug and a cylindrical part adjoining it and intended as a lodging for a draw plate, a draw plate comprising a fine stone having a central aperture for the jet of viscose and enchasing means for'securing the stone, said means comprising an enchase'd bottom edge of the I cylindrical hollows and a perforated elastic plug 'enchased in the same cylindrical hollow on top of the stone. i i In testimony whereof'I affiX my signature.
